Hello all! Our pool finally has water in it and we had our first swim. We went with Stonescape Minipebble from NPT (Tropics Blue). We love the color. We have found however, that there are a number of rough/raised spots, most of them being on the pool steps. Is there any way to smooth those out? One piece is probably protruding about 1/8" and is sharp. Can i file it down without causing any other damage? I can't imagine brushing it will help. Any other options/suggestions.

Thank you for any help you can provide!
